Application led September 12, 1921.

To @ZZ whom t may con-cern.'

Be it known that l, FinNs'r Vieron JUNGK, a citizen of the United Statesof America, residing at 442 Autum Avenue, Brooklyn, in the county ofKings and State of New York, have invented certain new and usefullmprovenients in l/Vashers, of which the following is a specification.

This invention relates to washers or bushings designed to be applied forexample, to the shafting of machinery, or to the shackle bolts on motorcars between the shoulder and the nut for taking up play between saidparts, without the removal of the nut or other holding member.

The object of my invention is to improve upon washers of thisdescription so that the two parts of the washer may be applied withoutloosening the bolt or atleast without loosening it more than thethickness of the washer, and at the same time to design a washer so thatthe two parts will be permanently locked together when once applied.

Further objects of the invention will appear as the descriptionproceeds.

Referring to the drawing in which what I now consider to be thepreferred forms of my invention are shown, Fig. l is a plan View of aremovable washer constructed according to my invention showing the keyto one side,

Fig. 2 is a plan view of the same showing it in the act of being appliedto a bolt or shaft, but before the key has been driven home.

Fig. 3 is a corresponding view after the key has been driven and lockedinto place.

Fig. 4 is a section on line 4 4 of Fig. l.

Fig. 5 is a detail view of a slightly modified form of key.

The main or body portion of my two part washer is shown at l, while thekey is shown at 2. The body portion is provided with the usual centralcircular aperture 3 the walls of which merge into the parallel sidewalls 4 and 5 of the lateral opening 6 permitting the washer to beinserted over the shaft or bolt 7 as will be readily apparent. At leastone of said parallel and preferably each wall is provided with a recessor nitch 8, 8', which extends beyond the periphery of the recess 3 toreceive the prongs 9, l0 of key 2 as hereinafter explained.

rlhe key portion has parallel sides 13 and 14 and is preferably curvedon outer rim or Serial No. 500,127.

edge to the same diameter as the periphery of body portion l. )The innerportion of the key is recessed to form one or more prongs 9 and l0.lWhile said recess need not be circular? the radius of curvature of thesame is less than the radius of the bolt 7 or of aperture 3, or inotherwords the distance a ig. l) between the inner ends of the prongs 9 andl0 is less than the diameter or cord by so that the prongs engage thebolt 7 as the key is slid radially into place (F 2). rlhe kev is thenstruck with a hammeripreferably, unltil the prongs are forced outwardlyinto nitches 8, 8 and the key is flush with the washer (Fig. 3).

lin Fig. 5, a slightly modified form of key 2 is shown wherein the easewith which the key may be driven into place is increased by reducing thethickness of the prongs 9', l0. rilhe body portion need be varied in noparticular since it is not necessary that the prongs completely fill thenitches 8, 8 when the key is in place as shown in Fig. 3. All that isnecessary is that the prongs or either of them be bent outwardly beyondthe parallel edges 13 and 14 to prevent the key from dropping out, asthe nut, when tightened will prevent all lateral movement.

Having described my invention what l claim and desire to secure byLetters Patent is:

l. A two part washer comprising an annular body portion having anopeningV in one side adapted to receive a bolt or shaft, a wall of saidopening having a recess therein, 'and a key member having a recessedinner portion forming a prong on a side thereof adapted to be expandedoutwardly into said recess by said bolt or shaft as the key is drivenhome.

2. A two part washer comprising an annular body portion having anopening' in one side adapted to receive a bolt or shaft, the walls ofsaid opening having opposite recesses therein and a key member having aprong on each side thereof7 the ends of which are of less distance apartthan the chord across said bolt or shaft between the points where theprongs engage the same, whereby said prongs are swaged outwardly intosaid recesses by said bolt or shaft as the key is driven home.

8. As an article of manufacture7 a take up washer or bushing comprisinga body portion with the usual central circular opening and out away onone side on parallel lines to form an opening for insertion of the boltor shaft, said parallel walls having nitches therein, and a flat keyhaving parallel sides for insertion into said opening and a recess atits inner portion forming opposite prongs, the radius of curvature ofsaid recess being less than the radius of said circular opening, wherebysaid key engages said bolt or shaft as it is forced into place and theop posite prongs are bent outwardly into said nitches.

4. Asl an article of manufacture, atake up washer or bushing comprisinga body portion with the usual central circular opening and cut away onone side to form a lateral opening having walls for the insertion of thebolt or shaft, said walls having portions thereof spaced farther apartthan the entrance to said lateral opening, and a fiat key havingstraight sides for insertion into said opening and a recess at its innerwhich are of less distance apart than the.

chord across said bolt or shaft between ,the

points where the prongs engage the same,

whereby said prongs are expanded 'outwardly into said recesses by saidybolt or shaft as .the key is driven home.

In testimony whereof signature.
